April 11, 2022. Following Clean Air Act requirements, EPA is proposing determinations for whether certain areas have met the 2008 or 2015 National Ambient Air Quality Standards (NAAQS) for ground-level ozone. Our proposals cover determinations regarding the air quality progress of seven nonattainment areas classified as “Serious” for the 2008 ozone NAAQS, and determinations for 31 nonattainment areas classified as “Marginal” for the 2015 ozone NAAQS. For areas not meeting the ozone standards, today’s proposals outline new timeframes and next steps for states to take to improve air quality. These proposals are based on a scientific evaluation of certified, publicly-available air quality monitoring data for the years 2018 – 2020. More details.
